John Frieda Brilliant Brunette Luminous Glaze, Colour Enhancing Glaze, Designed to Fill Damaged Areas for Smooth, Glossy Brown Color, 6.5 Ounce (Packaging May Vary) - 2 Pack

First of all this stains your hands immediately so I have started using gloves. That staining is inconvenient but is a testament to how well this adheres to your hair too. It covers grey! I have been blending my grey with a demi permanent (natural instincts) to avoid damage but that still uses some lift to deposit the color. This glaze just deposits. No lift. It basically stains your hair but it's a nice warm brown that really comes out well for me. I couldn't believe how well it doesn't far as grey coverage. I haven't had to dye my hair since I started using this and I'm probably 25% grey under it. I use it every other day. I mainly concentrate on my roots and then pull through my length and that works for me.
